Engineered for serious builds, this top-feed TGV housing kit for the 2001-07 Subaru WRX and 2008-17 Subaru WRX STI is machined from billet 6061-T6 aluminum on a 5-axis CNC machine, then finished in anodized silver for durability and aesthetics. It replaces the restrictive OEM TGV assemblies to free up airflow to the cylinder heads, supports both 11 mm and 13 mm injectors, retains factory fuel-rail mounting points, and comes complete with a pair of housings, O-ring gaskets and hardware for a seamless install. Built under PLM’s stringent enthusiast-driven quality standards, it’s the perfect upgrade for high-flow, high-boost Subaru turbo builds.
